Abstract

Penanganan pasca panen pisang ambon curup harus benar-benar diperhatikan, karena buah pisang Ambon Curup memiliki tekstur yang lembut dan mengalami proses pematangan yang cepat sehingga sangat mudah terserang infeksi dan penyakit pasca panen. Penelitian ini bertujuan untuk mendapatkan konsentrasi asap cair yang optimal untuk  mempertahankan kesegaran buah pisang Ambon Curup.Penelitian ini menggunakan asap cair dengan lima konsentrasi yaitu, C0 (asap cair 0%), C1 (asap cair 1%), C2 (asap cair 2%), C3 (asap cair 3%) dan C4 (asap cair 4%). Variabel yang diamati adalah, berat perbuah, berat persisir, warna kulit, warna daging buah, tebal kulit, rasa, tekstur, off flavor dan layak konsumsi / kesegaran, Hasil penelitian menunjukkan bahwa kesegaran buah terlama dapat dipertahankan sampai 14 hari pada perlakuan dengan konsentrasi 4%.

Abstract

The potential and dominance of the Bintangur Tree on Enggano Island is quite large. Bintangur seed  has a high oil content, and is not included in the food category. Bintangur oil is one of the vegetable oils that has the potential as a biodiesel feedstock. This study aims to determine the yield of Bintangur seed oil and the characteristics of crude oil produced. Bintangur seeds are obtained from the villages of Banjar Sari, Kaana and Apoho Enggano. Bintangur oil was extracted with n-hexane solution using soxlet. The oil characteristics observed included water content, density and free fatty acid content (FFA). The extraction results in the form of yellow oil with the yield of oil obtained ranged from 48.07 - 73.71%. Characteristics of crude oil produced has water content of 1.2 - 2%, density 0.910 - 0.920 and FFA 15.51 - 17.97%

Abstract

Midrib is one of the palm plantation  waste that has not been utilized optimally. The high cellulose content of palm midrib is potentially converted to carboxymethyl cellulose. This study aims to determine the characteristics of carboxymethyl cellulose that produced from various concentrations of trichloroacetic acid and reaction times. This study used a complete randomized design (RAL) with two factors i.e tricloroacetic acid concentration (10%, 20% and 30%) and reaction time (3 hours and 4 hours). The synthesis of carboxymethyl cellulose in this study consists of three stages i.e alkalization, carboxymethylation and purification. The carboxymethyl cellulose obtained was characterized include degree of subsitution (DS), pH, viscosity, water content, and purity. The results showed that the best carboxymethyl cellulose was obtained from the use of 20% tricloroacetic acid and 3 hours reaction time. The characterrization result include substitution degree value of 0.76, pH of 8.32, water content of 7.1%, with a  viscosity of 7.8 cP,   and purity of 92.62%.

Abstract

Bread is made from wheat flour and other ingredients whose dough is fermented and baked. Sweet bamboo flour is a food product made from sweet bread raw material with substitution variations in the concentration of bamboo shoot betung flour.  This study aims to determine the effect of bamboo flour substitution on the physical, chemical and organolytic properties of sweet bread. This study used Completely Randomized Design (CRD) consisting of one factor, namely the additon of   bamboo flour with concentration of 0%, 5%, 10%, 15%, 20% Each treatment was carried out 3 times so that the total number of experimental units was 15 units. The results showed that the addition of bamboo flour had an effect on the level of improvement of sweet bread with the highest value of 114.88%,  and the water content less than 40%. The brightness of the sweet bread color is found without the addition of bamboo flour with a value of 7.5 Y 9/4 and the darkest result is the addition of 20% bamboo flour with a value of 2.5 Y 3/6. Based on the results of organoleptic, the bamboo shoot flour significantly affected the color and texture of sweet bread but did not significantly affect the aroma, taste and overall.  The fiber content of sweet bread with bamboo shoot flour was higher than the control, namely 13.34-19.29% and the control 8.54%.

Abstract

This study aims to determine the effect of the method and time of extraction on the yield and characteristics of pektin red dragon fruit leather according to the SNI pektin (01-2238-1991) and the International Pektin Producers Association (IPPA) 2003. The experimentals design was a Completely Randomized Design with 2 factors. The first factor was the extraction method used, namely (M1 = conventional method, M2 = ultrasonik method). The second factor was extraction time (W1 = 15 minutes, W2 = 30 minutes, W3 = 60 minutes, and W4 = 90 minutes. The results showed that the extraction method had a significant effect on yield, equivalent weight, galacturonic acid content, degree of esterification, water content and ash content, but had no significant effect on methoxyl content. Extraction time significantly affected yield, equivalent weight, methoxyl content, galacturonic acid content, degree of esterification, water content and ash content. While the interaction of the two treatments had a significant effect on yield, equivalent weight, and water content. The highest yield was obtained using the ultrasonik method for 60 minutes with a value of 13.57%. The equivalent weight that meets IPPA (2003) and SNI pektin standards (01-2238-1991) is found in conventional and ultrasonik methods at 30 and 60 minutes.

Abstract

Processing of palm kernels at the kernel station of the palm oil mill still has a loss of kernel oil in the bulk silo kernel. This oil can be used as a raw material for solid soap. This study aims to determine the characteristics of solid soap resulting from core oil losses in terms of physical, chemical and organoleptic parameters and to obtain the right concentration of NaOH and fragrance oil volume to produce solid soap according to SNI 06-3532-2016. This study used a completely randomized design (CRD) with 2 factors, namely the concentration of NaOH and the amount of fragrance oil.

Abstract

Red Palm Oil Olein (RPOO), obtained from Crude Palm Oil (CPO) processing, can be a potential source of provitamin A due to its high carotene. Water degumming and Alkali refining are alternative methods that are not widely used to remove gum and Free Fatty Acids (FFA) in making RPOO with relatively low heating temperatures. This study aims to determine the effect of increasing the amount of NaOH during neutralization on RPOO yield, FFA levels, β-carotene content, vitamin A, and preference level for RPOO. This study used Complete Randomized Design (CRD) with one treatment factor, namely variations in the addition of the amount of NaOH. The results showed that the variation of the addition of NaOH had a significant effect on decreasing FFA RPOO to range from 0.24 to 0.07. The content of β-carotene produced ranges from (635.87 to 645.54 ppm) and the content of provitamin A ranges from (105.97 to 107.59 μgRE). In addition, the RPOO yield decreased with an increase in NaOH use, ranging from (53.24 to 42.26%). Organoleptic tests showed that adding NaOH significantly affects the level of liking for the color and aroma of RPOO. Increasing the use of NaOH in alkaline refining could produce RPOO with good quality, but at the same time, it could reduce the yield of RPOO produced.
